I don't speak Spanish, so I put that text into a translator and got a rough idea of what it was saying.

From what it looks like:
1) Carlos (Blizz support representative) never said you were banned for CrashFix2.
2) Carlos never said anyone was being banned for CrashFix2.
3) Carlos is not someone who would have access to finding the reason you were banned. It looks like he was just responding to what you said.

Here is an analogy:
-Blizz Jury sends you to jail for murder.
-You say: "Blizz, am I in jail because I stole bread? I needed the bread to feed my family!"
-Blizz Jailer says: "That is not an acceptable excuse."

Did you and your friends use any 3rd party programs besides CrashFix2?
